摘要： Disclosed is a method for production of lower olefins from a raw material containing dimethyl ether (DME), which can produce lower olefins (e.g. propylene) with good yield and in an economically advantageous manner by prolonging the time until the reversible deactivation of a zeolite catalyst and preventing the irreversible deactivation of the catalyst, can reduce the amount of water to be recycled to increase the thermal efficiency of the process, and can simplify the facilities and operations. Also disclosed is a method for improving the yield of propylene with good efficiency under practical operating conditions. A feed gas which comprises a DME-containing feedstock gas and an additive gas and further contains steam at a specific proportion is introduced into an olefin synthesis reactor to contact the feed gas with a zeolite catalyst, thereby producing a hydrocarbon product containing C2-C5 olefins. Propylene or the like is separated/collected from the hydrocarbon product, and at least a part of the remainder is used as at least a part of the additive gas.
